Steps out of a pair of trainers?

So, I bought an expensive new pair of trainers in the beginning of May. Due to having weird feet, most trainers are quite painful, and I've mostly kept to ecco shoes (not even their walking shoe variants). Towards the end of last year, I invested in some HOKAs, which resulted in me getting really painful feet that lasted for months (seems to have been plantar fascitis, but whatever).

So, in the beginning of May I went to this specialty shoes store and they immediately noticed that my feet are rather wide. They recommended some wider trainers, and it's been wonderful. Only downside is that they're expensive ($200). Best pair of shoes I ever had.

Notice the last word? 'had'. They're pretty much worn out, after a puny 3 months of use.

Checking fitbit, I've walked 1413980 steps since the beginning of May. Anyone with any idea of how many steps you should get out of a pair of good trainers?
